Hello guys, I've got a 2GB MicroSD in my G1... if I buy a brand-new 4GB MicroSDHC class 6, will I have some improvement in general performance of my phone? I have done the partitioning and all that kind of things... thank you!
assuming you are using a class 4 or lower then the answer you will get from XDA is mostly yes.
Some will agree and some will claim placebo effect but my personal opinion is the faster the better.
I've done some test and the maximum speed of my card is 6,4 mb/s.... will the new card improve the GENERAL performance of the ANDROID operative system? Or I will have only some stupid improvement in camera photo saving?

Depends.. the only advantage I see in upgrading your card without using it to store your cache or expanding the amount of apps you can have installed is watching and recording, video and photos, and more space for music or whatever miscellaneous files you choose to store and access
Ok thank you
Hi,
Has anyone tried either the Lexar or Patriot 32GB microSDHC card with their Droid/Milestones?
Any issues at all?
Thanks!
Any information at all would be appreciated.
I haven't been able to find any information by searching forums.
I am running Cyanogen 6, 2.2.1, so I should be able to format the 32GB card. I'm just concerned with compatibility issues with the original Droid 1 and the Milestone.
Anyone?
Thanks!
this would be interesting for me too. im searching a 32 gb card which is workin!
yeah, would love to hear something about 32gb goodness too ^^
Yeah I'm surprised that we aren't getting more feedback with this topic.
I've found threads with 32GB cards with EVOs and Droid Xs, but, that's about it.
I think it helps if you manage to get it formatted properly, either on a desktop computer or on your device (if it supports it).
I'm tempted by the Patriot 32GB Class 10, but, some of the people on Newegg seemed to have some issues with it on a their Droid Xs.
Im using a 32gb class 10 lexar microsd in my milestone, so far its working great and have had no problems

Thanks for the feedback!
Do you experience any subjective speed increases with the new card?
Have you run any SD Card speed tests with the card? If not, would you mind doing so and reporting back?
Just wondering if the Milestone will benefit from a class 10 card (or any card greater than class 2).
Thanks again!
i got 8.8MB/s write speed and 12.7MB/s read using antutu system review btw im also using apps2ext and cm7. I dont know by using apps2ext if the benchmark is effected. I was using a 16gb class 2 Kingston card before this and generally haven't noticed much of a speed difference but I mainly use the card for music
Edit: SD tools gets 10.6MB/s writing speed and 14.4MB/s reading speed

Hi,
Thanks for sharing your results. Those performance speeds are quite attractive!
I'm surprised that you you don't feel any subjective speed increases though. I would have thought that when accessing applications stored on your SD card, or when you initially remount your SD card and have to search through media using Gallery, that the difference would have been significant.
Although it is possible that our phones doesn't support much more than Class 2 speeds.
But, at least we know that the Lexar card is compatible with the Droid/Milestone!
Thanks very much for the information!

Class 2 is (roughly speaking) 2MB/s writing speed. Imagine you want to copy a lot of mp3's or a movie (or use it as USB dongle) with 2MB/s. unusable.

Oh sure, I understand that a faster card will make file transfers with my desktop much faster. I guess I was hoping to get more of a performance boost from my phone (ie. Apps2SD) with a faster card.
I'm not sure I'd call 2MB/S unusable for desktop file transfers. But, then again I don't change the music on my phone more than once a month. I can see it being more troublesome if you changed it more regularly. And hey, more speed is always good
Something else to consider - I have an 8GB class 2 card.
Loading angry birds seasons from my SD card = 15 seconds
Loading from internal memory = 9 seconds

Yes, that's a great point. I just don't know if the Droid/Milestone can take advantage of a microSDHC card with a higher transfer rate than Class 2.
Have you tried a faster card with your phone?
Does anyone have any comparison numbers with faster cards and application loading using Apps2SD?
Thanks!

Wow, impressive numbers. I wish the Droid/Milestone had half that performance
Is anyone using the Patriot 32GB with a Droid/Milestone?
With the Milestone SD card which came with the phone (I think this is a UK retail version) "OEM SD SU08G", I got these results:
3.8 / 14.8 MB/s
I added this simply to have something to compare with.
Will edit this image of the results in later: thumbnails37.imagebam.com/12224/fae506122237685.jpg

Hi,
Thanks for sharing your results!
You're the first person I've heard of who is using this combination. Your speed test results are very impressive.
May I ask you to clarify your comment regarding reboots? Do you mean that if you move large files, or a large quantity of files from your PC to your Milestone, that you have been experiencing reboots? What other issues have you been experiencing?
Have you noticed any kind of speed increase?
Thanks!

In my place, there are many persons who are using this sdhc, so don't worry MS can support it.
In our experenice from our fourm, some MS work great and nothing happened.
But, some MS including my MS have the problem about reboot, app exit when you are using it, if you move a large quantity of files once a time from PC to MS.
There is also a problem from my experenice, not for all others.
My MS could not identify the SD card, or need to format the Sd card.
In this situation, the SD card repairation by some sd format app could be settle the problem, and then the card is back. The information of the repairation shows that there are some unknow link, bad sector, or error link. When I look further, I find the files that often appear above three error message are in the below folders /sdcard/LOST.DIR and /sdcard/LazyList. Thus I think these are the reason why the problem happens.
There is an interesting thing. I have fat and ext partitions in my card, but the partition of ext never has any problems. Last month, I format the fat32 by 64K formation, and it works well so far. (someone prefers 32K)
The speed increase. Yes, but not so significantly. I feel the system is more smooth. The delay when open the app is also less, but you know the speed also involve the size of memory. So, it's haven't extreme different.
I saw a lot of complaints about lags, when the memory is filled, etc.
As we know, ssd performance degrades as it gets filled, that's true, however, project butter is based on a lot of caching.
I would suggest to keep your storage at least 15% free, and more importantly, check the cache size of your favorite apps, especially after a big write operation, like downloaded a hd movie or installed a large game. These kind of operations tend to take space aggressively, leading to cache performance suffering. Just clear the cache if the cache is big.
I've been using chrome intensively for the past week (the first week with my n7), chrome had built >200mb cache already. I cleared it, now my n7 is like butter flying again.
i dont get where you get off saying that performance decreases when the SSD is filled up. I had my nexus 7 filled up almost to the max (16gb) and it didn't lag one bit. It's probably just the babies around here that like to complain everything that are experiencing the lag. what about the other two hundred and forty million people out there not complaining?
It has been proven that the lag exist and if you haven't experienced then good for u. Half of the people will never experience because not all of users will fill up space fully. Other half doesn't know about existence of this forum and lag thread etc.

sure the lag exists... but he's saying it's due to storage issues. I personally don't think so; SSD do not lag, they might take .5 milli second to read through, but so what? we've become a generation of no patience. There must be some other issue regarding the lag that people are experiencing. I can almost 100% guarantee its not the SSD
Some apps collect memory when they run for long periods of time and start to hog the system down.
However, the main culprit in Android lag is the way it treats UI rendering. It has nothing to do with how much an ssd is filled.

Project butter has triple caching for cpu, gpu, display. Ui rendering is gpu and display related, it needs caching too. Do you now where it's the cache from? It's part of ssd.

Ssd cannot get that magic latency number all the time. It needs memory banks to increase throughput. It has to have enough space for memory banks, if there is not enough space left, the throughput and latency will suffer. This can explain some larger ssds are faster than smaller ones, with the same everything else.

I understand what you're saying, however, the speed at which a SSD will read is gonna be faster, regardless of these memory banks; I'm sure thats why when they release a 16gb version of a device and you only get 13gb, it has to be accounted for something. they do not have 3gb worth of worthless OS apps. i'm sure that's saved up storage for extra memory.

Storage capacities mentioned by retails usually follow 1000MB = 1GB, whereas the true value is 1024MB = 1GB. This is one cause for lower then reported size available.
Another reason is, possibly, the space just isn't accessible. For example, I have a 500GB HDD. Only 465GB is usable. Regardless if the 500GB reported is 1000MB=1GB or 1024MB=1GB, 465GB is still falls short. And this is with a complete drive wipe too. My 80GB HDD also does this (74GB usable), and I'm almost certain 99% of storage media does this too (I have yet to see any storage device listed that has the exact amount of storage usable as specified on the box).
To further what I mentioned above, the storage chip used isn't as static with usable storage space when manufactured. What I mean is, one 16GB SSD chip might have a few MB difference on usable space then another 16GB chip of the same make. To compensate for this, and to keep a uniform device specification, the partition is just locked at 13GB usable.
I have a feeling storage media is just marked to what "nice" number it rounds to, regardless if it has that much or not (16GB = 20GB, 91GB = 100GB, etc.).

i will second the OP's cache fix and say it worked for me as well. my Chrome cache was up to 144MB and reboots would not fix the constant lag, so i cleared the cache, rebooted, and it was back to blazing fast for me.

You seem to be confusing the Nexus 7's emmc storage for a high speed ssd. It is only capable of ~15MBps read and write.
Depending on how cache is chunked (assuming it even is), it could easily cause the lag people are seeing.

Actually, the term Gibibyte (GiB) is now used for 1024 values in storage - although you're right about it being due to manufacturers.
A 500GB hard drive will always be 465GB, you're right that 1GB = 1000MB, but you also need to take into account that 1MB = 1000KB and 1KB = 1000B.
If you do the sums, you'll find the exact difference is always 7% (by dividing 1 by 1. 024 three times) . Which is why you'll find 465 is 93% of 500, and the same for 74 of 80.

It's because of certain apps which are running. When mine starts to lag, I clear caches and stop apps. Mine wouldn't lag before I installed a few new apps in the past couple weeks. could be news360 or pulse or flipboard. Could also be nexus 7 media importer. Mine never lagged before I installed any of those.
My lag had gotten bad. Androbench showed SQL speed in 1 or less. But I've found a workaround which really 1000% improves it. Running Francos kernel with fsync off...
Makes a HUGE difference for me in all apps. Especially Facebook and TiVo.

Don't even bother filling. Encrypt and watch the speed drop to 1/10 on a blank fresh install. :/ deal breaker for me, unfortunately. I have to be able to encrypt and won't put up with a tablet that feels two years older than it is.
These are after encryption and before. Clean machine with 4.1.1 and everything killed. In a day with 2 or three things installed, the encrypted result halves.

I had bought a Nook HD+ to be the replacement for my aging 1st generation Kindle Fire (Otter) tablet. However after having had it for 6 months now I've been rather disappointed with it. On paper it should have been better than my OG KF in every way but in reality that has not been true.
Nook HD+
Released 2012
1.50GHz TI OMAP 4470 (ARM Cortex A9 + PowerVR SGX 544)
1 GB of memory
32 GB storage (controller without issue too)
CM11 Nightly 2014.08.02 installed to internal storage
Davlik, stock kernel, not overclocked
Kindle Fire
Released 2011
1GHz TI OMAP 4430 (ARM Cortex A9 + PowerVR SGX540)
512 MB of memory
8 GB storage
CM11 Nightly 2014.08.02 installed to internal storage
Davlik, stock kernel, not overclocked
Whenever it comes to anything relating to the screen though this old as dirt KF tablet still performs better than this much newer and on paper better device. The Nook HD+ is obviously better as most apps perform much better like browsing FB app, looking at web pages with lots of content, running any number of non-visual intensive apps.
Places the Nook HD+ bogs down.
Paging around in the home screen stutters when loading icons even if the page has already been loaded.
Closing an app and returning to the home screen is extremely sluggish and then requires reloading of each page.
The boot animation is completely embarrassing, it jitters and skips like it's been beaten to death.
Scrolling through large pages of data in Chrome jitters rather badly.
Some games with intensive video requirements are just nasty at times. Running really slow or slowing down over time.
This video shows the KF next to the Nook HD+ to show how horrible the start animation is. After loading I page left then right and you can see the home page stutter on loading the icons when I come back left.
https://www.youtube.com/watch?v=PEJK-VUZunk
This video shows loading PvZ 2 where just the loading screens alone are running slower and jitter more. Then when loaded menus take longer to load and are very jittery compared to the KF.
https://www.youtube.com/watch?v=XCG8GKIWyso
Note - I even removed the overclock from the KF for these tests.
I realize the resolution is greater on the HD+ than the KF but the Amazon KF HD 8.9" uses the same hardware as the HD+ and it doesn't have the same issues. I also recall when running the stock firmware the system was much more responsive than it is under CM11 (any version).
This really seems like a lack of a good video driver or something wrong with the memory management.
I'm looking for serious discussion on this and not "well mine works fine so it must be yours..." or suggestions of running some random ROM or running TRIM or tweaking some random setting. This is something more than basic settings as I've already tried several over the last 6 months along with fresh installs of CM.
Your hd+ looks normal. I wouldn't think about it too much as its more than likely not getting better than that.
I just bought a new phone and the hardware made android so much more snappier then it was on the last one no matter how much people had tweaked the roms.
Just how it is. Its a cheap tablet with a nice size screen and hardware not quite capable.

I've installed CM11 for two of my friends on their HD+'s, and their is snappier than mine. All are fresh installs. There is a very noticeable difference between mine (purchased in June, 2013), and theirs (purchased in May & June 2014). I didn't write everything down, but there was very little difference in the information for each device as reported by Quadrant.

You maybe experiencing lag since you have been running longer (since 2013, not just with CM11). Also you may have a different emmc chip than they do. There are hardware differences between some devices

Thanks for the info. I'll ask them to send me the device info and I'll compare them both. Based off of what you said earlier, it may be due to too many writes to the chip? If so, I can live with that. I did abuse the heck out of it.

That is exactly what I meant. But if you run CM11 enough, it may speed up due to it running TRIM in the background.

Idk. Had two of these, one for three months and this one since around when you got yours. It performs as I remember and as I expect.
But since your comparing directly to another aren't ALL electronics that way? This display is more blue than that one, this hard drive has more errors that that one. This cpu can be oc'd more than that one.
There's always things causing speed differences. Background services, amount of free space - its best to have >50% free space, amount of installed apps, what leapinlar pointed out, etc.
In one month they could have no noticeable difference. Tis all I'm saying.

I suggest doing when you won't need your phone for a few minutes and also make sure to plug your phone into power to help it go faster.
Once it is done, I suggest testing one or two apps to make sure they work. Then I would reboot your phone one more time. (This seems to fix a noticed app lag after the update). Once it comes back up, use your phone as normal and enjoy the free speed boost and a little added battery life. I have not noticed any issue with the 168 apps on my Nexus 5 nor any stability issue with the device, but again you millage may vary on your device and apps."
Some additional notes:
I stress doing a full recovery backup first. If you don't have enough internal space available, then that may cause it to be unusable when android starts up due to it failing while configuring art.
Phones (and other low internal storage devices) are a bit problematic due to amount of space available. My htc sensation couldn't enable art from not enough internal space. But the nook hd+ (for instance) has plenty (assuming its not all used).
Art is supposed to be enabled automatically in the next android release.
"With the L Developer Preview, ART is now the default runtime."
https://developer.android.com/preview/api-overview.html
Art requires more space due the fact that apps are pre-compiled during install:
"ART, on the other hand, uses an Ahead-of-Time compiler (AOT) to process application instructions before they're needed so things run more smoothly for the user."
http://lifehacker.com/android-art-vs-dalvik-runtimes-effect-on-battery-life-1507264545
You'll possibly lose about half a GB or more. It just depends on how many apps including the apps included with the rom.
The reason why the hd+ has poorer performance is probably due to it dragging a 1920x1080 (2073600 pixels) screen while the Fire has a 1024x600 screen (614400 pixels). Processing a full 1080p screen vs a 600 makes a big difference. The 544 isn't much of an upgrade over the 540 to make up for it. While it doubles the frame rate in graphics by about 2x over the 540, its having to push more than 3x the pixels.
Apple had the same issue with the ipad 3 when they went to the retina screen. It was a bit of a dog on pushing the retina screen, hence the quick rollout of the ipad 4 with a much faster cpu and gpu.
Lastly, amazon has a lot of pretty good paid developers optimizing the heck out of the Fire. I doubt its running a stock google display/graphics driver.
One of the things with high density displays. They're pretty and nice for text but you need plenty of horsepower to run them.
I signed up for alerts but doesn't seem like I was getting them.
I was comparing it to the OG Kindle Fire because it was the first real Android tablet and it's old as dirt now. Also as mentioned in the other performance vs stock thread when running the default Nook HD+ OS the interface is a lot more responsive and games perform better too. It seems like there's something missing between those kernel's/drivers and the CM version.
Of note these commits might help us with some of our issues. It looks like they're enabling a 128 MB swap partition for this device.

Total noob here, so please go gently on me. I've searched the Nook HD/HD+ General Forum and could not find any threads on this- forgive me if I missed them.
I'm on my second HD+. The first one would overheat and shut down. I've seen online that this is a common problem. The new (recertified) one also heats up in the lower left quadrant when using a browser, but it hasn't shut down (yet).
I've tried CM11 on SD just for fun, but it freezes several times an hour on me, which makes it hard for me to give Kitkat a fair trial. Honestly, I don't have any issues with the Nook stock ROM. I've put Holo Launcher on it, and it does everything I want to just fine (photo frame, reading, simple games, videos, etc.).
I would be willing to root and/or EMMC CM ROM if it would help with the overheating issue without sacrificing stability or battery life.
Any ideas?
Thanks!
Heat issues
I had heat issues with stock and all CM11 roms. However....Pac Rom seems to have solved the issues.
Go here for how to : http://forum.xda-developers.com/showthread.php?t=2705381
I've tried many of these ROMs and am using this with ZERO problems. Don't forget to turn off location services and be chincy with apps you let run in the background. No CNN widgets.

I am using the latest TWRP .... http://forum.xda-developers.com/nook-hd/development/recovery-unofficial-twrp-2-7-1-0-t2828280
Not sure if this will flash with CM recovery...Think so..just not sure.
Either way...Pac Rom has been the best so far for my Nook HD+

They all get a little warm in the lower left the CPU is there and they don't have fans. It should not get so hot as to be uncomfortable though.

In my experience CM10.x and CM11 run noticeably cooler than stock ROM.
What brand & class of SD did you use? Generally class 4 is better than class 6 or 10 for running ROM off SD -- see http://forum.xda-developers.com/showthread.php?t=1005633 for discussion of comparative performance of different SD makes/models for the purpose of hosting ROM.
Thank you all for your help. I guess if it doesn't shut down, I can live with it warming up a bit.
Have any of you had any instability issues with the ROMs you're currently using? Any effect on battery life?
The SD card I'm using is a SanDisk 16GB class 4 micro SDHC. I played with it some more today, and it's no better- still freezes quite often.

I never liked running ROMs on any SD cards because the internal memory is usually much faster on these sort of devices. I'm not 100% sure (maybe someone who is can chime in), but I believe that you're not going to have TRIM support with a SD card so the system is going to slow down over time.
Thanks ryanl2299. I'm only running on SD as a trial. I realize that running it on EMMC would be faster and more stable. But I have seen in forums that some people still have problems running ROMs on EMMC.
If the overheating issue becomes more of a problem (i.e. random restarts/shutdowns), I just want to know if there are any apps or ROMs which would improve the overheating issue. If there are any ROMs which would help, I most certainly do an EMMC install (as long as I'm not trading one problem for another due to the ROM being unstable).
Thanks again for everyone's input!

Technically, the stock ROM is not much different than Pac-Roms or CM10 or CM11 or Vanir, Omni or Android box Wasser. Sure there are elements that differ from device. We all need to be able to freely change to custom ROMs for our device and go back and forth. It's like overclocking your pc. The stock B&N Rom can be backed up and restored. Always do a back up on good SD card. Perhaps even upload your backed up ROM to a cloud source.
I will probably die with my HD+ in my hand.
Vanilla Droid is always best.

How you use it will effect heat more than any rom will (think games vs reading).
Though, I'm wondering if down clocking the cpu would help or hurt.
Or how about art instead of dalvic. Chrome instead of firefox. low brightness vs. full brightness, in 90 degree weather vs indoors. Etc. Course all that could be included under how you use it as well and all of it can affect heat output.
I have never worried about overheating when used within reason - they should not overheat except for a factory defect or outside of reasonable conditions of which the latter should be covered under technical boundaries and common sense. If your in direct sun and it feels too hot then move the device into the shade. etc.
ART didn't work
Switched to ART on my Nook HD+ using pac_ovation 4.4.4 08252014. The tablet works amazingly well with Dalvik. ART seems fine....can't tell much difference in speed. Wish this tab had a quad core. Truly good stuff with Omniswitch and Slim Recents along with the app bar. Love it.

Sorry to hijack the thread. Do you feel PAC gives you better smoother performance. What score do you get with antutu 5?
Do you still get screen flashing if you don't disable hardware overlay?
I'm running cm11 and it's OK but always looking around [emoji1]
Thanks.
